How to stop the RadialMenu from opening?
When you click the navigation button, the SfRadialMenu opens automatically. This can be manually stopped by forcing the RadialMenu to remain closed. To achieve this,
- Retrieve the navigation button in the SfRadailMenu, and hook its MouseLeftButtonUp event.
- Handle the event by setting e.Handled=true.
This restricts the SfRadialMenu from opening.
The following code example demonstrates the same.
Xaml
<navigation:SfRadialMenu x:Name="radialMenu" Loaded="radialMenu_Loaded"> <navigation:SfRadialMenuItem Header="Cut"/> <navigation:SfRadialMenuItem Header="Copy"/> <navigation:SfRadialMenuItem Header="Paste"/> </navigation:SfRadialMenu>
C#
public partial class MainWindow : Window
{
bool CanOpen = false;
public MainWindow()
{
InitializeComponent();
}
private void radialMenu_Loaded(object sender, RoutedEventArgs e)
{
radialMenu.Loaded -= radialMenu_Loaded;
Button navigationButton = radialMenu.Template.FindName("PART_NavigationButton", radialMenu) as Button;
if(navigationButton!=null)
{
navigationButton.PreviewMouseLeftButtonDown += navigationButton_PreviewMouseLeftButtonDown;
}
}
void navigationButton_PreviewMouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
if (!CanOpen)
{
e.Handled = true;
}
}
}
